• Earthquakes of Type 1 (Ms ≥ 5.5, or ML ≥ 5.8), • 40 strong motion histories in case of stronger earthquakes in Montenegro, • Records on soil type A.

ELABORATION OF MAPS FOR CLIMATIC AND SEISMIC ACTIONS FOR STRUCTURAL DESIGN IN THE BALKAN REGION 27-28 October 2015, Zagreb Horizontal elastic spectral response for:

• Earthquakes of Type 2 (Ms < 5.5, or ML < 5.8), • 732 strong motion histories in case of weaker earthquakes in Montenegro, • Recorded on soil type A.

90 % of records in case of earthquakes with ML < 4.5

ELABORATION OF MAPS FOR CLIMATIC AND SEISMIC ACTIONS FOR STRUCTURAL DESIGN IN THE BALKAN REGION 27-28 October 2015, Zagreb Comparisons of horizontal elastic spectral response shapes: recommended vs. calculated shapes

As the data base of strong motion records is still relatively small, for now we decided to keep recommended shapes.

ELABORATION OF MAPS FOR CLIMATIC AND SEISMIC ACTIONS FOR STRUCTURAL DESIGN IN THE BALKAN REGION 27-28 October 2015, Zagreb Vertical elastic response spectra for:

• Earthquakes of Type 1 (Ms ≥ 5.5, or ML ≥ 5.8), • 20 strong motion records, • Records on soil type A.

ELABORATION OF MAPS FOR CLIMATIC AND SEISMIC ACTIONS FOR STRUCTURAL DESIGN IN THE BALKAN REGION 27-28 October 2015, Zagreb Vertical elastic response spectra for:

• Earthquakes of Type 2 (Ms < 5.5, or ML < 5.8), • 221 strong motion records, • Records on soil type A.

Again – small number of records with ML > 4.5

ELABORATION OF MAPS FOR CLIMATIC AND SEISMIC ACTIONS FOR STRUCTURAL DESIGN IN THE BALKAN REGION 27-28 October 2015, Zagreb SOIL CLASIFICATION:

General classification was accepted, but detailed explanation of soil type was determined - appropriate to the regional geological characteristics of the territory of Montenegro

ELABORATION OF MAPS FOR CLIMATIC AND SEISMIC ACTIONS FOR STRUCTURAL DESIGN IN THE BALKAN REGION 27-28 October 2015, Zagreb Question on low and very low seismicity { EN98-1: 3.2.1(4) and 3.2.1(5)}

There are no areas characterized as very low or low seismicity in Montenegro

3.2.2.5(4)P Design spectra for the case of horizontal component of seismic action, is defined as:

Value of 0.2 was adopted as lower factor β for design spectra - as recommended in EN98-1

At the end of 2014 National Annex for Eurocode EN1998-1 (nMEST EN 1998-1 2014) was adopted by the Technical Committee of the Montenegrin Institute for Standards and now is available for the implementation.

ELABORATION OF MAPS FOR CLIMATIC AND SEISMIC ACTIONS FOR STRUCTURAL DESIGN IN THE BALKAN REGION 27-28 October 2015, Zagreb EDUCATION

For Montenegrin Chamber of engineers the education of members is one of the most important tasks. Since 2006, the Chamber organized and financially supported numerous activities related to the implementation of Eurocodes: through seminars, round tables, conferences, lecturing, publishing related educational materials, etc.

According to the Action Plan of the Montenegrin Government on implementation of Eurocodes, Chamber of Engineers was appointed as the institution responsible for education of engineers in Eurocodes implementation. We will continue with organizing educational seminars in next two years.

ELABORATION OF MAPS FOR CLIMATIC AND SEISMIC ACTIONS FOR STRUCTURAL DESIGN IN THE BALKAN REGION 27-28 October 2015, Zagreb CLIMATIC MAPS

Climatic data were processed and climatic maps prepared, but still in raw form.

It is expected that National Annex for EN 1991 will be finalized and prepared for adoption until the end of this year Average snow height
